The salt-alkalization desertification land area formed by both primary and secondary salt-alkalization has extended in a large scale, which has become a significant eco-environmental problem. Based on the characteristics of eco-environment and the situation of desertification in westem Songnen plain, this paper reports the analyzes of its formation in background and cause. An early waming system on the salt-alkalization desertification is established and the GIS technology is used to abstract the information of desertification evaluation index. Supported by the integrated technology of the GIS and ANN, the orientation and quantitative result of desertification are gained, which is helpful to the eco-environment protection and resource development in westem Songnen Plain.展开更多

Apart from the study of the impacts of climate change on health which requires a longer consideration, a special emphasis is given to the area of weather-related services based on biometeorological forecasting. A new way of understanding the interaction between atmospheric factors and living organisms is presented and some biometeorological indexes already developed are shown. Customized biometeorological services must be constructed in the field of human health based on the ICTs development and the amount of climatic data available but new approaches and scientific methods are required to success in achieving this enterprise.展开更多

文摘Desertification is an environmental issue in the world. The salt-alkalization desertification land area formed by both primary and secondary salt-alkalization has extended in a large scale, which has become a significant eco-environmental problem.

文摘The following paper is a brief theoretical approach to the state of the art in relation to the new demands of society in the area of climate and weather-related services for health. Apart from the study of the impacts of climate change on health which requires a longer consideration, a special emphasis is given to the area of weather-related services based on biometeorological forecasting. A new way of understanding the interaction between atmospheric factors and living organisms is presented and some biometeorological indexes already developed are shown.
